My apologies, I meant 1.7.7.1 (have only just set the site up) and just checked and PHP is 7.3.
Thanks for your help its greatly appreciated. When I asked the theme provider they said they could see the boxes no problem and sent me a screenshot. I have tried in Edge and Chrome but neither works. I am going to try on my works laptop (if I can) to see if it is maybe my device.
